did you really just say his "pressure test" done at a the shop won't reveal anything unless hot? umm...the test is under Pressure

as a matter of fact you are suppose to do the test first when cold and then started if you are to find some head gasket leaks.
The test is under pressure, but the sum of heat + pressure is greater than just pressure alone. Remember, we're talking cracks invisible to the naked eye
